Note 164 — Chapter III · THE SPREAD OF ISLAM AMONG THE CHRISTIAN NATIONS OF WESTERN ASIA.

These details from the first two centuries of the Hijrah are meagre in the extreme and rather suggest the existence of proselytising efforts than furnish definite facts. The earliest document of a distinctly missionary character which has come down to us, would seem to date from the reign of al-Maʼmūn (813–833), and takes the form of a letter164 written by a cousin of the caliph to a Christian Arab of noble birth and of considerable distinction at the court, and held in high esteem by al-Maʼmūn himself. In this letter he begs his friend to embrace Islam, in terms of affectionate appeal and in language that strikingly illustrates the tolerant attitude of the Muslims towards the Christian Church at this period. This letter occupies an almost unique place in the early history of the propagation of Islam, and has on this account been given in full in an appendix.165 In the same work we have a report of a speech made by the caliph at an assembly of his nobles, in which he speaks in tones of the strongest contempt of those who had become Muhammadans merely out of worldly and selfish motives, and compares them to the Hypocrites who while pretending to be friends of the Prophet, in secret plotted against his life. But just as the Prophet returned good for evil, so the caliph resolves to treat these persons with courtesy and forbearance until God should decide between them.166 The record of this complaint on the part of the caliph is interesting as indicating that disinterested and genuine conviction was expected and looked for in the new convert to Islam, and that the discovery of self-seeking and unworthy motives drew upon him the severest censure.
